3 Claims. (Cl. 68-440) This invention relates to washing machinesfor use :in commercial laundries and'dry cleaning establishments, the machines embodying an outer stationary washing ,orcleaning fluid receiving drum and an inner rotatable clothes receptacle drum, and has for .its object a particularly simple construction as to the assembly of theframe and outer drum and as to the actuation of the washing drum by power actuated rollers within the outer drum on which rollers the inner drum rests. More specifically, it has for .its object a washing machine construction which includes a base ,frame .provided with one or more transverse hollow boxlike saddles or troughs having their upper sides openand .the edges of the side walls along the open sides arcuataan outer cylindrical drum of the same radius as the arcuate edges and seated on saidarcuate edges and secured to the saddles-or troughs, and also having slotsreg- ,istering or alined with the inner open sides of the saddles, and power actuated rollers, usually .of a soft yielding material, as rubber, in the end portions of the boxlike saddles, and projecting into the outer drum, and an inner perforated clothes receptacle or drum within theouter drum and resting on the peripheries of the rollers, so as to be annularly spaced from the outer drum and to be actuated about its aXis by the rollers.

The inventionconsists-inpthe: novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is bad to the accompanying drawings, in which like characters designate corresponding parts in all the views.

Figure 11 .is a plan view, partly broken away, of this washing machine.

Figures 2 and 3 are, respectively, end and ide elevations, both partly in section, of the washing machine.

Figure 4 is a fragmentary exploded view illustrating the assembly of the outer drum on the saddles.

Figure 5 is a side elevation on a reduced scale, parts being removed, of a slightly different arrangement of the power actuated rollers from that shown in Figure 3.

l designates the base frame and 2 transverse boxlike saddles on the base frame and open at their upper edges, as at 3, the upper edges of the side walls of the boxlike saddles being arcuate. 4 designates an outer cylindrical drum of the same radius as the arcuate upper edges of the saddles 2, these being seated on and secured to the upper edges of the saddles, as by rivets '5.

The outer drum 4 is provided with slots '6 in their lower sides, registering and alined with the pperopen sides of the saddles 2. l designates .an inner perforated clothes receptacle or ,drum

mounted within thelouter drum 4, as willbe presently described, and movable about aihorizontal axis ,in thecleanin-g or washing fiuidin the .outer drum 4. Ribs H are provided to liftland ,drop

articles placedin thedrum l. The inner drum J :is mounted as to be spaced radially from the inner cylindrical wall of the outer drum .4 .and to have clearances between its end walls and the-end wall .ofthe outer stationarydrum l. The inner drum 1 is provided with annaxial loading and unloading door opening at ,8 and the outer drum is provided, with asimilar openingat .9 which is normally closed ,by a hinged door lil of any suitable construction. The door Hlis-of such diameter that the ribs 1 protrude slightly into the opening 8. The outer drum is also-formed with :a dump valve controlled .outlet .H .in its lowermost portion and-also with a vent opening 1-2 in itstop portion.

l3 and I4 designate, respectively, power actuated rollers ,looatedat opposite sides oi the frame. As here shown, there are two pairs ofsuch rollaers, the :units 13 and of which are located-in the opposite end portions of. the 'boxlilce saddles. In "the form shown in Figures 1, 2 and 3, there are two pairsof rollers 13, 4. located at opposite ends of the main frame. The rollers areof a yielding or rubber-like material. The inner drum 1 rests on said rollers, and the rollersproject a sufiicient distance into the outer drum =4, providing an annular space between the two drums- "The rollers 13 of each pair are mounted upon a shaft l5 common to the rollers l3 and the rollers I t of each pair are likewise mounted upon a shaft i6 common to them. The shafts I5, it are preferably actuated by motors il, l 8 mounted on brackets projecting from one end of the base frame, the shafts of the motors being connected to the adjacent ends of the shafts I5, 15 by suitable couplings I 9 and 20.

As here shown, each shaft iii, it includes end sections 2!, 22 or Elli, are, which are the axles for the two rollers 13 and the two rollers l4, respectively, and the axles are connected to the intermediate portion of the shafts It or iii by universal joints designated generally 23, which are operable to permit the uncoupling of the axles 2t. 22; cm, are from the intermediate portions of the shafts l5, it for the purpose of mounting or demounting the rollers therefrom. The forward and rear ends of the shaft l5 are mounted in bearings HI and 222, and of the shaft [6 in bearings 223 and 224. These bearings are mounted so that the shafts l5, it are easily removable therefrom to remove rollers I3 and M. The end walls of the saddles 2 are provided with openings 25 of larger dimension than the rollers to permit the placing and removing of the rollers in the saddles 2, these openings being provided with demountable closures 26. With the couplings 23 uncoupled, the end sections of the shafts I5, I6, which are the axles for the rollers I3, M, can be moved axially out of the rollers, permitting the rollers to be removed. The rollers may be remounted on the axies in the reverse of this operation. Each set of rollers l3, I4 prefer-ably coaot with raised tracks 21 and 28 on the inner drum 1, the tracks registering with the open sides of the saddles 2. The rollers are thus located in the washing fluid but actuated by power and motion transmitting means located outside the fluid.

In Figure 5 a single track 210 is shown located midway of the ends of the inner drum and coacting with a single pair of rollers I30. In this construction, the base frame is provided with but one boxlike saddle and the rollers are not only of sufilcient width or axial length to provide the necessary traction between them and the track 210 but also to limit the rocking movement of the inner drum during its rotation. The supporting rollers are spaced apart horizontally such distance that the inner drum 1 wedges slightly between the rollers, which are resilient, thus providing ample driving traction. A shown, the rollers are in radial lines of the drum 1, which meet at the axis" of the drum at a 90 angle. Water, hot or cold, is fed to the machine through a conduit 30 and supplies necessary for washing are fed through chamber 3| having a door 32.

An observation or sight glass 33 indicates the level of water in the machine.

Owing to this arrangement of the inner drum and the rollers in the boxlike saddles, not only is the construction particularly simple and eflicient but also the arrangement is such that in this type of washer, an inner clothes receptacle is actuatable by rollers on which the receptacle rests, as the rollers run in the washing fluid. Heretofore, washers with this type of roller drive were called shell-less washers, embodying but a single drum, which not only receives the washing or cleaning fluid but also serves as the clothes receptacle. The type of shell-less washer has, however, certain marked disadvantages. The inner and outer drum washer here shown has all 4 the advantages of a shell-less washer and none of the disadvantages.

What I claim is:

1. In a washing machine, a base frame, an outer stationary cylindrical fluid receiving drum carried by the base frame, the base frame having hollow boxlike portions communicating with the interior of the drum through individual openings in the cylindrical wall of the drum at spaced apart locations, power actuated rollers located in the hollow boxlike portions of the base frame and projecting through said individual openings into the drum, power means for actuating the rollers located outside of the hollow boxlike portions of the frame and outside of the outer drum, and a perforated washing drum located Within the outer drum and resting on said rollers and operable about 'an axis by said rollers.

2. In a washing machine, a base frame provided with a hollow boxlike saddle open at its top and having the upper edges of its side walls arcuate, an outer stationary cylindrical fluid receiving drum seated on the saddle and secured thereto and conforming to the arcuate edges of the side walls of the saddle, the outer drum hav-- ing openings alined with the upper open side oi the saddle, power actuated rollers mounted in the. end portions of the boxlilge saddle and having their peripheries projecting into the outer drum and a perforated washing drum located within the outer drum and resting on said rollers and operable about an axis by said rollers.

3. In a washing machine, a base frame provided with hollow boxlike spaced apart saddles open at their tops and having the upper edges of their side walls arcuate, an outer stationary cylindrical fluid receiving drum seated on the saddles and having openings alined with the open tops of the saddle, power actuated rollers located in the end portions of the boxlike saddles and having their peripheries projecting into the outer drum and a perforated washing drum located within the outer drum and operable about an axis, the inner drum being spaced from the inner walls of the outer drum and resting on the peripheries of the power actuated rollers.
